Definitions

  • the invention relates to a method for the closed-loop or open-loop control of a forced-induction internal combustion engine.
  • German Reference DE 40 25 901 C1 has disclosed an exhaust turbocharger for an internal combustion engine that has a turbine with a turbine geometry that can be varied by means of variable turbine guide vanes and a compressor driven by the turbine for increasing the boost pressure in the cylinder inlet.
  • the turbine guide vanes can be adjusted by an actuator so that the effective turbine cross section of the turbine is modified. This makes it possible to achieve different exhaust backpressures in the section between the cylinders and the exhaust turbocharger, depending on the operating state of the internal combustion engine, thereby allowing the output of the turbine and the output of the compressor to be adjusted according to requirements.
  • the turbine guide vanes are adjusted to a desired boost pressure in accordance with specified characteristics.
  • boost-pressure control is performed in accordance with different characteristics above and below a threshold value for the exhaust backpressure. This makes it possible to prevent the occurrence of uncontrolled increases in pressure in the exhaust line upstream of the turbine while the boost pressure is still rising after a positive load change. The internal combustion engine no longer has to expel the exhaust against an increased exhaust backpressure and efficiency is increased.
  • German Reference DE 195 31 871 C1 Another method for closed-loop control of the boost pressure is known from German Reference DE 195 31 871 C1.
  • this publication proposes to determine the difference between the exhaust backpressure and the boost pressure as the controlled variable for closed-loop control in order to adjust the boost pressure. This makes it possible to detect an impermissibly high deviation in the exhaust backpressure in the case of a positive load change and to correct it by suitable measures. measures.
  • the problem underlying the invention is to optimize the operating behaviour of the engine over all load and engine-speed ranges.
  • open-loop control is exercised in the lower load/engine-speed range and closed-loop control is exercised in the upper load/engine-speed range.
  • the division into an upper and a lower load/engine-speed range with the respectively assigned characteristic maps has the advantage that it is possible to decide, by comparison with a defined specifiable limiting value, whether open-loop or closed-loop control should be performed.
  • By distinguishing between open-loop and closed-loop control it is possible to follow an optimum strategy appropriate to the respective operating situation while allowing for partially contradictory aims.
  • closed-loop and open-loop control By switching between closed-loop and open-loop control according to requirements, the operating behaviour of the internal combustion engine can be optimized with regard to fuel consumption and dynamic response.
  • Open-loop control also has advantages in terms of fuel consumption compared with closed-loop adjustment in the lower load/engine-speed range.
  • Open-loop specification of the turbine's position avoids a situation where the turbine geometry is moved into the pressure build-up position and the exhaust backpressure upstream of the turbine is increased. This avoids the need to increase fuel injection to allow the exhaust to be expelled into the exhaust line against the exhaust backpressure.
  • the pressure level is higher, favouring closed-loop control and thus also allowing changing external influences to be taken into account.
  • the boost pressure rises steeply as a function of the actuating travel of the turbine geometry, so that even small changes in the actuating travel lead to a large change in the boost pressure.
  • open-loop control would be too inaccurate because dimensional inaccuracies due to wear, thermal expansion and forced-induction would lead to an impermissibly large deviation from the desired value. Closed-loop control can compensate for such inaccuracies.
  • the position of the variable turbine geometry is stored as a function of load and engine speed in the associated characteristic map in the lower load/engine-speed range.
  • the position of the turbine geometry or actuating-signal values that are fed to the actuator acting upon the turbine geometry can be specified.
  • desired boost-pressure values are preferably specified as a function of the load and engine speed.
  • the position of the variable turbine geometry is varied until the actual boost-pressure values coincide with the desired values.
  • closed-loop control can also be performed by way of the engine speed.
  • desired engine-speed values are stored in the characteristic map as a function of the load and compared with actual engine-speed values. Setting of the desired values is performed by varying the position of the turbine geometry in a similar manner to that for boost-pressure control.
  • FIGS. 1 a - 1 c shows an engine-speed/torque diagram with different ranges for closed-loop and open-loop control and associated boost-pressure characteristics
  • FIG. 2 shows a block diagram of an open-loop control system for the variable turbine geometry
  • FIG. 3 shows a block diagram of a closed-loop control system for the boost pressure.
  • a limiting value can be specified for the load and/or engine speed to differentiate between the lower and the upper load/engine-speed range.
  • the currently applicable load/engine-speed range can be identified by means of an engine parameter—expediently the current load or engine speed in the unit corresponding to the limiting value.
  • Each load/engine-speed range is assigned a characteristic map.
  • the system switches to the other load/engine-speed range with the respectively associated characteristic map.
  • Either the load or the engine speed or a combination of load and engine speed can be used as the limiting value or engine parameter.
  • the VTG is subjected to open-loop control in accordance with a characteristic map assigned to this range, in which flap positions are stored as a function of load and engine speed when a flap-type turbine is used.
  • the boost pressure is subjected to closed-loop control in accordance with a characteristic map in which desired boost-pressure values are stored as a function of load and engine speed.
  • the torque variation is limited at the bottom by a minimum curve 3 and at the top by a maximum curve 4 .
  • the lower range 1 is assigned a boost-pressure curve 5 from FIG. 1 c , which represents the variation of the boost pressure as a function of the adjustment of the VTG at an arbitrarily chosen operating point 6 within range 1 .
  • the VTG is in its open position, in which the effective turbine cross section is reduced to only a minimal extent, if at all.
  • the VTG is in its pressure build-up position, in which the effective turbine cross section is reduced to the greatest possible extent.
  • the boost pressure rises only slightly, in accordance with the boost-pressure curve 5 plotted, as the adjustment of the VTG increases, there being virtually no dependence between the boost pressure and the adjustment of the VTG, with the result that closed-loop control of the boost pressure through adjustment by means of the VTG would have little effect, if any, in this range.
  • open-loop control of the VTG is therefore carried out in accordance with the characteristic map assigned to this range.
  • the operating point 8 plotted is assigned a boost-pressure curve 7 as a function of the adjustment of the VTG in accordance with the FIG. 1 b .
  • the boost-pressure curve 7 rises steeply as a function of the adjustment.
  • closed-loop control of the boost pressure is carried out to enable the actual value of the boost pressure to be matched precisely to the desired value and to allow deviations caused by dimensional inaccuracies, wear, expansion etc. to be compensated for.
  • closed-loop control of the boost pressure it is also possible to carry out closed-loop control of an engine-operating or state variable that exhibits linear or non-linear dependence on the boost pressure.
  • closed-loop control of the speed of the charger in which case desired values for the speeds of the charger are specified as a function of the load and/or engine speed as the upper characteristic map.
  • a turbine with an axial slide, a turbine with radial guide vanes or a flap-type turbine can be used to give the VTG.
  • FIG. 2 shows a device, illustrated as a block diagram, for open-loop control of the VTG in the lower load/engine-speed range.
  • a first characteristic map 10 Stored in an engine control and regulating unit 9 is a first characteristic map 10 , in which values for the positions of the VTG or values corresponding to these positions are stored as a function of the engine load M L and the engine speed n.
  • the engine load M L and the engine speed n are applied as input signals to the engine control and regulating unit 9 , and, as an output signal, the control and regulating unit 9 supplies a pulse-width-modulated actuating signal S St , which is fed as an input signal to an electropneumatic converter 11 , which produces a control pressure p D as an output signal.
  • control pressure p D is fed to the actuator 12 of the VTG as an input pressure, and, in accordance with the control pressure p D applied, this produces an actuating travel s, which is applied to the VTG of the exhaust turbocharger 14 of the engine 13 .
  • FIG. 3 shows a device, illustrated as a block diagram, for closed-loop control of the boost pressure in the upper load/engine-speed range.
  • the engine control and regulating unit 9 includes not only the characteristic map 10 assigned to the upper load/engine-speed range but also a controller 15 , which is embodied as a PI controller in the exemplary embodiment shown. Desired boost-pressure values p 2S,soll are stored in the characteristic map 10 as a function of load and engine speed. As a function of the input signals M L for the engine load and n for the engine speed, the desired boost-pressure values p 2S,soll are compared with actual boost-pressure values p 2S,ist , which are detected in the engine 13 and are fed to the control and regulating unit 9 .
  • the difference ⁇ p 2S between the desired boost-pressure value and the actual value is fed to the controller 15 , in which the actuating signal S St is produced as a pulse-width-modulated output signal in accordance with the given control algorithm. Subsequently, the actuating signal S St is fed to the converter 11 in a corresponding manner to that for open-loop control in FIG. 2, and, if appropriate, is subjected to pressure regulation in the controller G R , and the control pressure p D produced is fed to the actuator 12 . The actuating travel s of the actuator 12 is then applied to the VTG of the exhaust turbocharger 14 .
  • the method described can be used both for forced-induction internal combustion engines for commercial vehicles and for passenger cars.
  • the method can be employed for spark-ignition and diesel engines.
  • the method is preferably employed in the powered driving operating mode but it may also be expedient to exercise open-loop or closed-loop control in engine braking mode in various indicated operating states.
